Most of the zombie and mutant animals were stronger than the human-turned zombies, so he was very happy to face them.
They were faster and stronger, so dealing with them would take more effort from him.
He wanted to strengthen himself, so fighting stronger beings like zombie animals and mutant animals was very good for him.
Unfortunately, there were only a few zombie animals and mutant animals that he had encountered in the past few days.
But he didn't mind the lack of them, because as they got closer to the next place that they had to go to, the number of zombies was also increasing.
So, even without the zombie and mutant animals, it still became a bit harder for him to move farther, and he couldn't move as fast as he did when he was just starting, because the number of zombies was increasing and their strength was also growing.
The number of level 2 zombies was steadily rising as they got nearer to their destination.
